Paranasal sinuses refer to sinus areas near the nose. The paranasal sinuses are lined with cells that create mucus, which is important in keeping the nose moist while breathing and fighting off infection. The nose opens up into what is called the nasal cavity, which has two passages that allow air to move through while breathing. It is here, within the lining of the sinuses and nasal cavity that these types of cancers form.
There are several paranasal sinus areas including:
- Frontal sinuses: Located in the lower forehead above the nose.
- Maxillary sinuses: Located on both sides of the nose.
- Ethmoid sinuses: Located beside the upper nose, between the eyes.
- Sphenoid sinuses: Located behind the nose, toward the middle of the skull.
